Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To obtain a phthalide compound useful as a coloring agent for pressure-sensitive recording materials or heat-sensitive recording materials by oxidizing a triarylmethane compound under specific conditions. SOLUTION: A triarylmethane compound of formula II is oxidized with at least one kind of an oxidizing agent selected from air, oxygen, hydrogen peroxide and a mixture of oxygen with inert gas in the presence of an alkali hydroxide at pH of reaction solution adjusted to 9.5-11.0 to provide the objective phthalide compound of formula I (R<1> to R<6> are each an alkyl or R<1> and R<2> , R<3> and R<4> , R<5> and R<6> may mutually br connected to form a heterocyclic ring with N). Adjustment of the pH is preferably carried out by adding an acidic substance such as sulfuric acid and/or an acidic gas such as carbon dioxide to the reaction solution in which pH is raised according to progress of the reaction. Progress of the reaction is promoted by jointly using diatomaceous earth, zeolite or a metal compound as a catalyst.  Thereby, the compound of formula I is obtained in a short time, high yield and purity.

Title: Vehicle-borne cooling device
Inventor: FURUSE HIDEKAZU
IPC: F25D19/00
Filed: 1989-06-13
Abstract: PURPOSE:To compact the whole while smoothly flowing an air current by a cooling fan by housing each constitutional equipment of a high pressure unit into a hollow cylindrical body. CONSTITUTION:A cooling fan 17, a driving power supply 7, a condenser 12 and a compressor 11 are disposed successively into a hollow cylindrical body 6 in the axial direction. An air current by the cooling fan 17 can efficiently cools the driving power supply 7, the condenser 12 and the compressor 11 installed into the hollow cylindrical body 6, and a function as a high pressure unit can be displayed sufficiently.

Filed: 1984-07-23
Abstract: PURPOSE:To perform recording and reproduction stably by continuing recording operation until a track being recording when a stop signal is inputted is recorded completely even if the stop signal is inputted in the middle of the recording. CONSTITUTION:A flip-flop 50 and an AND gate 51 are further added to the conventional recording timing control circuit. When the recording is stopped in its middle, the stop signal outputted from a system control 29 is inputted to the flip-flop 50, whose output Q goes up to a high level when the stop signal is inputted.

The flip-flop 45 is switched from the high level to the lower level when this reset signal is inputted, stopping the recording operation.
